java - 带有 jax-rs : BeanCreationException 的 REST 服务

Question

你好，我有 apache cxf 和休息服务(使用 jax-rs 和 spring)的问题。

我正在尝试发布一个休息服务:userService

错误是:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Invocation of init method failed; nested exception is org.apache.cxf.service.factory.ServiceConstructionException

服务接口(interface):

@Path("v1")
public interface UserService {
    @GET
    @Path("user")
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    public User getUser();
}

服务实现:

@Service("userService")
public class UserServiceImpl implements UserService {

    public User getUser() {
        User u = new User();
        u.setFirstName("plop");
        u.setLastName("plop");
        u.setEmail("plop@plop.com");
        u.setUuid("1");

        return u;
    }

}

非常感谢您的帮助!这个问题要了我的命!

Answer 1

我认为你的问题出在这里:

<jaxrs:server id="userService" address="/">
    <jaxrs:serviceBeans>
        <ref bean="userService" />
    </jaxrs:serviceBeans>
</jaxrs:server>

您正在创建一个名为“userService”的 bean，它引用一个名为“userService”的 bean。也许将 jaxrs:server 端点的 bean 名称更改为与“userService”不同的名称？
